• Mobile devices are emerging as primary design point for end-user access to IT

• More than a new access point to view existing back-end systems

• Mobile First is about: Behavior like consumer applications

• constantly connected clients• quickly accomplishing single tasks and then move on

• Is accelerating the integration of cloud, social, and analytics


Mobile First - Mobile Applications are Not Miniature PC applications…

Mobile Applications PC Applications

Usage Context

� User may be in the middle of some other

activity (e.g. shopping in a supermarket)� Using the application is the primary activity

� Interactions are short and may be

interrupted� Interactions are longer and more focused

� Users are very impatient � Users are impatient

Mode of Interaction

� Non-keyboard: touch prevalent, also

speech� Keyboard and mouse

� Typing should be minimized � Typing is okay

� Screen size/real-estate is small� Larger screen size for presenting

information

Other considerations

� Integration with device capabilities (e.g.

camera, GPS, accelerometer)

� Offline behavior

IBM Worklight - Consistent Mobile End-user Experience

Part of the IBM MobileFirst family - Mobile Application Platform for smartphones and

tablets

� Simplifies the development of mobile applications

� across multiple mobile platforms - iOS, Android, BlackBerry, and Windows® Phone

6

Typical Customer Pain Resolved with Worklight: •First mobile app was created through expensive native development by 3 parties

•No consistent user experience across mobile platforms

•No code reuse between mobile and PC environments

•User was required to install multiple apps - impossible to update existing app without

redeploying the entire native app


Leverage common HTML5

and mobile libraries/frameworks:

Need to use familiar web technologies:

• HTML5, CSS, JavaScript

Plus (Hybrid applications)

Support all major mobile platforms with proprietary tools, languages and APIs:

Worklight Components Overview


Worklight Server

Worklight Server is a WebSphere Application Server (WAS)/Java application,

supported on System z Linux – WAS 7, 8, 8.5 on SLES 10, 11, and RHEL 5, 6

Adapters are used to communicate to back-end services like databases,

transaction systems, MQ, etc.

Performs protocol mediation - JSON is used to communicate to mobile devices –

translation is done to HTTP or Web Services that are used by server components.

Caching Mechanism

Universality• Supports multiple integration technologies and back-end

information systems

Read-only & Transactional Capabilities• Adapters support read-only and transactional access

modes to back-end systems

Security• Flexible authentication APIs for back-end connections

• Connected user identity control

Caching• Leveraged to store data retrieved from back-end

Transparency• Uniform exposure of back-end data for all adapter types

Fast Development• Defined using simple XML syntax

• Easily configured with JavaScript APIs

Adapters


Worklight Studio - developing adapters

� An Adapter is a transport layer used by the Worklight Platform to connect to various back-end systems.

– Executed on Worklight server– Implemented in JavaScript by default

• Can be custom-coded in Java– Simple client-side JavaScript invocation model

through Worklight client API

� Adapters are used for:– Retrieving information– Performing actions

� Out of the box Adapter support:– HTTP Adapter (supports both REST and SOAP)

• You can use the HTTP adapter to send GET, POST, PUT, and DELETE HTTP requests and retrieve data from the response body. Data in the response can arrive in XML, HTML, or JSON formats. JSON (JavaScript Object Notation) is the newest format developed for mobile communications.

Mobile Access Security

IBM Security Access Manager for Cloud and Mobile extends user access protection to

mobile and cloud environments using federated SSO, authenticating and authorizing the user

and their device

Ensuring users and devices are authorized to access enterprise resources from that specific device.

Notes:

Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the

workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.

This information provides only general descriptions of the types and portions of workloads that are eligible for execution on Specialty Engines (e.g., zIIPs, zAAPs, and IFLs) ("SEs"). IBM

authorizes customers to use IBM SE only to execute the processing of Eligible Workloads of specific Programs expressly authorized by IBM as specified in the “Authorized Use Table for IBM Machines” provided at www.ibm.com/systems/support/machine_warranties/machine_code/aut.html (“AUT”). No other workload processing is authorized for execution on an SE. IBM offers SE at a lower price than General Processors/Central Processors because customers are authorized to use SEs only to process certain types and/or amounts of workloads as specified by IBM in the AUT.
